become due and payable forthwith without further demand or notice.

such sale or transfer has been registered under the Act and applicable state
securities laws or unless the Company has received an opinion of counsel or
other evidence satisfactory to counsel to the Company to the effect that such
registration is not required because an exemption from such registration is
available.

         6. Conversion. (a) The Payee shall have the right at the Payee's
option, at any time prior to payment of the Note, to convert all, or any part,
of this Note into such number of fully paid and non-assessable shares of the no
par value common stock (the "Common Stock") of the Company as shall be provided
herein. The Payee may exercise the conversion right provided in this Section 6
by giving written notice (the "Conversion Notice") to the Company of the
exercise of such right and stating the address to which the certificates
evidencing the Common Stock shall be delivered. The Conversion Notice shall be
accompanied by this Note. Except as provided below in this Section 6, the
Company will issue one share of Common Stock for each $.80 of then outstanding
principal balance of and interest accrued on this Note upon conversion of the
Note (the "Conversion Price"). Conversion shall be deemed to have been effected
on the date the Conversion Notice is given; provided, however, the conversion
privilege of this Note may not be exercised by, and the Common Stock shall not
be issued to, the Payee if such conversion would be unlawful. As a condition to


                                      -1-

conversion, the Company may require the Payee to sign a representation of
investment intent letter confirming compliance with applicable federal and state
securities laws and other applicable laws, and receive satisfactory assurance
that issuance of the Common Stock will not violate law. Promptly after receipt
of the Conversion Notice and confirmation of compliance with law, the Company
shall issue a stock certificate of the Company representing the number of shares
of Common Stock to which such Payee is entitled and a check in payment of all
accrued interest unpaid on the Note up to and including the date of the
Conversion Notice unless the Payee has indicated that it also wishes to convert
the accrued interest into shares of Common Stock.

                  (b) If the Common Stock issuable upon conversion of this Note
shall be changed into the same or different number of shares of any other class
or classes of stock, whether by capital reorganization, reclassification or
otherwise, appropriate adjustment shall be made to the conversion rate. Similar
adjustment shall be made in the event of any reorganization, merger or
consolidation.


         7. Notices. Any notice or other communication given hereunder shall be
given in writing and sent by overnight courier or registered or certified mail,
return receipt requested, addressed to the Company or the Payee at their
respective addresses as set forth in the Note. Notices shall be deemed to have
been given four business days after the date of mailing or one business day
after delivery to an overnight courier. The address for notices for any party
may be changed by notice given pursuant to this Section 7. For purposes of this
Note, "business day" shall exclude Saturdays, Sundays and legal holidays in the
State of Colorado.

performance shall be governed in all respects by the laws of the State of
Colorado.

         9. Miscellaneous. All powers and remedies given by this Note to the
Payee shall, to the extent permitted by law, be deemed cumulative and not
exclusive of any power or remedy or of any other powers and remedies available
to the Payee, by judicial proceedings or otherwise, to enforce the performance
or observance of the agreements contained in this Note. No delay or omission of
the Payee to exercise any right or power accruing upon any default shall impair
any such right or power or shall be construed to be a waiver of any such default
or any acquiescence thereof. The Company waives presentment for payment,
protest, the filing of suit or the taking of any other action for the purpose of
fixing its liability for payment of the Note.
